Snow Leopard sold nearly twice as many copies as Tiger and Leopard in first few weeks

Apple is selling its latest Mac OS Snow Leopard at a very brisk pace according to reports from research firm NPD. NPD reports that the sales of Snow Leopard have far exceeded the sales of the previous operating systems Leopard and Tiger.

According to numbers gathered by NPD, Apple has sold nearly twice as many copies of Snow Leopard as it did Leopard and almost four times as many copies compared to Tiger. Another important metric for Apple is the fact that while sales of Snow Leopard have decreased since the first week the OS was offered, the decrease hadn't been nearly as significant as the past two OS updates over the same period.

NPD reports that Snow Leopard has seen sales decrease about 25% after its first week of release. Leopard and Tiger sales decreased by about 60% after the first week of availability in comparison. Stephen Baker from NPD said, "Even though some considered Snow Leopard to be less feature-focused than the releases of Leopard or Tiger, the ease of upgrading to Snow Leopard and the affordable pricing made it a win-win for Apple computer owners — thus helping to push sales to record numbers."
